About the training

Scala is the modern functional programming language whose name underlines its biggest advantage which is the scalability. Scalability of Scala is the consequence of the functional and object-oriented programming merging. The construction of Scala language is meant to satisfy Java programmers” needs and is supposed to increase the productivity and lower the costs at the same time.

Introduction to Scala enables to learn the most important elements and components of the language in just 2 days. The completion of the training provides you with a chance to begin your work with a  rapidly developing and up-to-date programming language.
